Application filed April 24, 1911. Serial No. 622,899.

To all whom it may concern:

Be it known that we, ELDA G. SMITH and FLORIAN J. MANTEL, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Incandescent-Electric-Lamp' Fixture, of which the following is a specification.

()ur invention has for its object the production of a fixture for supporting incandescent electric lamps arranged in a wall of a car or other structure, when not in use and movable out of said wall to be brought into service; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had'to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a front elevation of this fiX- ture when in operative or open position. Fig. 2 is a rear elevation thereof, the parts being shown as in their inoperative or closed position. Fig. 3 is avertical sectional View of the parts shown in Fig. 1. Figs. 4 and 5 are plan views, partly in section, of parts shown respectively in Figs. 1 and 2. Figs. 6 and 7 are horizontal sectional views of the fixture, the same being shown as in its operative or open position, in Fig. 6, and in its inoperative or closed position in Fig. 7.

This fixture comprises, generally, a frame adapted to be hinged to a wall having an opening therein and to support and maintain an incandescent electric lamp in vertical position, the frame being movable about its axis for carrying the lamp from within the wall to the outside thereof.

Usually the fixture also includes wings or plates carried by the frame and arranged at an angle to each other and extending in a radial direction relatively to the axis of the frame, the wings or plates serving as reflectors for the lamp when the fixture is in operative or open position and also as doors for closing the opening in the wall 'when the frame is swung to either of its other parts of the fixture and obviously may be omitted, if desired, and the remaining parts of the fixture supported directly by the Wall 1.

5 is theframe-pivoted at 6 to the base plate 3 and comprising wings or plates 7 and 8 arranged in planes at an angle to each other,'and also extending in substantially radial directions relatively to the axis 6 ofthe frame, the plates having concave reflectmg portions 9, 10, respectively.

11 is a spring tending to swing the frame on ts pivot 6 from its closed to its open position, that is from its position shown in Figs. 2, 4 and 7 toward that shown in Figs. 1, 5 and 6.

12 is an incandescent electric lamp suitably supported by the frame 5 as hereinafter described, and 13 is'a top plate extending between the wings 7, 8 and being usually fixed relatively to the plate or wing 7.

'I he wing 8 is movably supported by the 1113301 part of the frame 5, and is here shown as pivoted at 14 between its side edges to arms 15 forming part of the frame 5, the arms of the pivot 14: preferably extending parallel to, and being spaced apart from, the axis 6 of the frame 5. A spring 16 normally tends to move the plate or wing 8 on 1ts' pivot 14 to advance the outer margin thereof (that is the margin farthest removed from the axis 6 of the frame 5) into the position shown in dotted lines, Fig. 7, so that the outer margin will engage suitable limitmg means as the rear face of the plate 3, when the frame 5 is swung by the spring 11 into the position shown in F ig..7. During further opening movement of the frame by hand the margin engages and fulcrums at 17 onthe inner face of the wall or plate 3. Thus the wing or door 8 moves about two axes located at opposite sides of the open %he wing or plate 8 is provided with a forwardly extending bracket 18 at its upper end, such bracket being arranged close to the lower face of the top plate 13 and being provided with a depending socket 19 for supporting the lamp 12 with its axis parallel to, and in advance of, a straight line passing through the axes 6 and 17 of the bracket 5 and the door or plate 8 respectively. Said plate 8 also carries a suitable bracket 20 on its rear side upon which is carried a pair of contacts 21, 22 on opposite sides of the pivotal axis 14 of the door 8.

Said contacts 21, 22 are movable into engagement with contacts 23, 24 fixed relatively to the wall 1, and here shown as carried directly by the base plate .3. The contacts 23, 24 are connected in circuit with a suitable source of supply of electric energy and the contacts 21, 22 are connected wires 25 respectively to the terminals of the socket 19,

During the swinging of the frame 5 outwardly by the spring 11 from the position shown in Figs. 2, 4 and 7 to that shown in Figs. 1, 3 and 5, the Wing or plate 8 is tilted on its pivot 14 by its spring 16 until its outer margin is in advance of the inner margin, and engages the rear face of the base plate 3 in advance of the opposlte margin of said plate, as indicated in Figs. 5 and 1.

During such movement the contact 21 -en-.

gages with its corresponding contact 23 While the other contact 22 is out of engagement with the contact 24-, After the frame 5' has been swung by the spring-11 to the position shown in dotted'lines Fig. 7, the frame is moved by hand by applying force to the Wing or door 7, thereby causing the wing or door 8 to fulcrum at its outer margin on the plate 3 and also slide laterally until said plate 8 reaches the position shown in Figs. 3, 5 and 6, bringing the other contacts 22, 2d into engagement so that the lamp 12 is in a closed circuit and is located in front of the center of the plate 8. Q

The frame 5 is normally prevented from movement by the spring 11 by means of a spring-pressed catch 26 Fig; 3, having an engaging end 27 which enters a socket 28 in the upper face of the topplate l3, said catch consisting of an angular'lever pivoted at its angle at 29 between lugs provided on a push button socket 30 which'i's' carried by the base plate 3 and contains a suitable push button 31 operable for tilting the catch 26 on its pivot. I

During the outward movementof the frame 5 the engaging end 27v of the catch bears on the upper face of the top plate 13.

To close the fixture, pressure is applied to the door 7 and during the initial movement of the frame 5, the outer margin of the door 8 is restrained from movement during the initial part of the closing movement of the frame, in order to move the door 8 relatively to the frame 5 and carry the lamp from the position shown in Fig. 5 to that occupied in Fig. so that the lamp will not strike the plate 3. The door is restrained at its outer margin in any suitable manner and is here I shown as held by a shoulder 32 opposed to 60 ing a shank which is rigid with the plate.

the rear face of the plate 3 and usuallv hav- As the frame 5 is swung outwardly the outer margin ofthe door 8 clears such shoulder and such margin does not pass under the shoulder until the frame is moved by hand sleeping cars and is particularly advantageous in that the lamp and fixture are confined in minimum space and the lamp is always supported in vertical position so that the liability of injuring the filament thereof is reduced to a minimum. Furthermore, owing to the pivotal movement of the support for the lamp relatively to the frame a smaller wall opening is required than if a lamp support, rigid with the swinging frame, were employed.
